W. F. CAGWIN METHOD AND APPARATUS FOR CLEANING SOOT OUT OF GAS MAINSFiled May 26. 1923 VAX/mm f fym/d w or other sealing material during theno'rmai operation of the gas producer and that this loam is removed andthe blow pipes inserted therethroug'h so that the soot is removed fromthe entire gas main by beginning at the opening nearest the gas producer10 and continuing in successive stages until the entire length of pipehas been traversed and the soot removed into the combustion chamher-,andthat after each successive operation the opening through which the pipeis inserted is sealed, and that the entire operaion is completed withoutdiscontinuance of the operation of either the gas producer or thefurnace.

While I have described more or less precisely the details ofconstruction, I do not wish to be understood as limiting myself thereto,as I contemplate changesin form and the proportions of parts and thesubstitution of equivalents as circumstances may suggest or renderexpedient without departing from the spirit or scope of my invention.

I claim:

1. The method of removing soot from mains containing combustible gas anddi posing of the soot which comprises progressively blowing the sootfrom the inlet end of the gas mains toward and. out of the outlet end ofthe said gas main and. into a furnace, and burning the soot removed fromsaid gas main in the combustion chamber of the furnace.

2. The method of removing soot from mains containing combustible gas anddis posing of the soot which comprises apply- 111g in said mam atsuccessive spaced omts throughout the extent of the main, fiuid un dersuperior pressure, said applications lee-- mg progressive along thedirection of flow of the gas, Where the soot is blown along with thegas, and blowing the soot out of the outlet end of the main and into a.furnace, and burning the soot in the-furnace.
